Vehicles without interface can be converted using the enclosed interface board, size of the interface board approx. 65mm x 40mm In addition, a speaker box is included, but other speakers suitable for the electrical values can also be connected. Compared to the previous decoder, the performance data has been significantly increased, and it offers much more functions and programming options.
